论文摘要
在海洋地震反射调查中，大多数数据仅包含水文阵列获得的压力。获得的数据受到频率带宽的限制，这是由于表面反应的幽灵信号与人工资源（如气枪）产生的地震信号相关的污染所引起的。这项研究开发了一种利用镜像效应来控制这些信号的方法，并使用虚拟地震源在反映实际来源的位置生成的信号对地下结构进行图像。处理结果表明，分解的幽灵信号可以被视为附加的调查数据，以增强信噪比和扩大带宽。
In marine seismic reflection surveys, most data comprise only the pressure acquired by a hydrophone array. The acquired data are subject to frequency bandwidth limitations caused by the contamination of surface-reflected ghost signals associated with seismic signals generated by artificial sources such as airguns. This study developed a method to exploit the mirror-image effect to control these signals and image the subsurface structure using signals generated by virtual seismic sources at locations mirroring actual sources. The processing results indicate that decomposed ghost signals can be regarded as additional survey data to enhance the signal-to-noise ratio and widen bandwidth.
